Brilliant (click to enlarge). Hat-tip Matt Wardman over at Anna Raccoon's. It's an online visualisation of US Government Debt starting from a single 100 dollar bill right up to the 114.5 trillion US unfunded liabilities: go here: wfynoway. Equally good is the one of the sources for this figure (another source being the US Federal Reserve of course!): USdebtclock.org - "see the debt in real time" (but also figures for population, stats, money supply, deficits, workforce, tax etc).
